1 Definition
1.1 Definition
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

5 Formation
5.1 Formation
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

All about Shale and Boninite Properties

Know all about Shale and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Shale belongs to Sedimentary Rocks while Boninite belongs to Igneous Rocks.Texture of Shale is Clastic, Splintery whereas that of Boninite is Aphanitic to Porphyritic. Shale appears Muddy and Boninite appears Dull and Soft. The luster of Shale is dull while that of Boninite is vitreous. Shale is available in black, brown, buff, green, grey, red, yellow colors whereas Boninite is available in bluish - grey, brown, colourless, green, grey colors. The commercial uses of Shale are creating artwork, pottery and that of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
